Different fertilization methods for different vegetables

Basal fertilizer must be rotted and basal fertilizers are generally manure, compost and other farmyard fertilizers. Before the vegetables are sowed or planted into the soil before planting, these farmyard fertilizers not only contain a variety of elements required for vegetables, but also provide a large amount of organic matter in the soil and improve the soil. Farmers used as basal fertilizers must be fully decomposed, and basal fertilizers have both full and partial application methods. Root vegetables, spinach, leeks, and other closely planted leafy vegetables, as well as a large amount of application, can spread manure, compost, etc. evenly onto the ground and plough them into the soil. For pumpkins, eggplants, cabbages, etc., where there is a small amount of crops or manure, etc. with relatively small amounts, it is possible to conduct trenching between rows or digging holes between plants. After the application of basal fertilizer, it is necessary to spray photosynthetic nutrient film fertilizer at the emergence stage of vegetables to increase the photosynthetic production of nutrients and chlorophyll, help plants absorb a lot of light, light, light, compatible with conventional fertilizers, and nutrient supply to plant growth and development to the limit.

Fertilizer top dressing to be flexible to fast-acting fertilizer-based, such as human waste, ammonium sulfate, compound fertilizer, urea and so on. After 3-4 true leaves or planted seedlings of vegetables have survived, topsoil is applied after each application. The number and amount of topdressing should depend on the type of vegetables, growing season, climate, soil moisture, and fertility. When the plants are small, the fertilizer concentration should be thin, and the amount of one application can be less, and the number of fertilizers can be gradually increased as the plants grow. Fertile soil, strong vegetable growth, can be applied less, on the contrary, you should give more. Usually topdressing once every 15-20 days. For the growing fruit of the vine, it should be sprayed with intelligent control to promote the growth and nutrition matching during the fruit growth period, fill in the vacuum of the lack of nutrients, inhibit the growth of shoots, and increase the nutrient supply of the fruit. Fast-growing vegetables, such as spinach and pakchoi, should be applied thinly and should be applied every 7-10 days. In short, topdressing should adopt the method of “first lighter, thicker, and less food” and timely top-dressing multiple fertilizers in stages to meet the nutritional needs of vegetables in different growth periods.

Different types of vegetables require different fertilizers. Cabbage and other leafy vegetables must be supplied with sufficient nitrogen to grow quickly. Beans, potatoes, etc. should be given more potassium fertilizer in order to increase production and quality. Tomatoes, eggplants, melons, etc., in addition to the application of nitrogen fertilizer, should be more phosphorus and potassium fertilizers, in order to promote fruit growth, early maturity and improve quality.
